App1ication filed August 21, 1928. Serial No. 583,340.

The invention relates to vehicle wheels and refers particularly toadevice for securing a demountable I'lIIl upona disk wheel body. One ofthe objectsofithe invention is to provide a simple form of clamp whichis engage-able with the demountable rim and disk andprovided with meansfor positioning itself concentrically upon the wheel body. With this andother objectsin view, the invention resides in the novelfeatures ofconstruction as more fully hereinafter set forth.

In the. drawings:

Fi ure 1. is a side elevation of a vehicle whee embodying my invention;.

Figures 2 and 3 are cross sections res ectively on the lines 22 and 3--3of igure 1.

1 is the hub, 2 the disk forming the wheel body, and 3 the demountablerim. The disk has the inner annular portion 4 detachably secured to theannular flange 5 of the hubby the nuts 6 threadedly engaging the outerends of the bolts 7. which are secured to the annular flange. The diskhas the inclined outer edge portion 8 forming a flared seat engageableby the correspondingly inclined face 9 of the bead 10 near the inneredge of the demountable rim. 11. is the outer annular portion of thedisk connectin into the inclined outer ed e portion and in turnconnected into by t e outwardly dished ortion 12 which latter forms ineflect a bea 13 is the inwardly dished portion of the disk connectingthe outwardy dished portion and the inner annular portion of the disk.

To clam the demountable rim u on the seat formed by the outer inclined ege portion 8 of the disk, I have provided the transversely splitchannel-sha ed ring 14 through the base of which the b0 ts 15 freelyextend. These bolts extend transversely of the outer annular portion 11of the disk and are fixed- 1y secured thereto by suitable means such asolygonal portions 17 of the bolts passing through the outer annularportion. Nuts 18 threadedly engage the outer ends of the bolts and abutthe outer face of the base of the ring. The rin has the outer sideflange 19, the edge of w ich is engageable with the outer face of thebead 20 nearthe outer edge of the demountable rim, the face beinpreferably inclined towardthe demounta 1e rim in thedirection of thecentral plane of rotation or plane of impact. The ring also has theinner side flange 21 which has at its edge the sheared divergingoutwardly and inwardly inclinedfoot flanges 22 and 23 respectively,which are preferably curved to fit the curvature of the outer face ofthe beadformed by the outwardly dished portion12 of the disk. Theinwardly extending foot flanges 23 are positioned radially inward fromthe bolts 15 and preventthe inner side flange of the ring from ridingover the. radial outer face of the outwardly dished portion of the disk,while these inwardly extending foot flanges with the outwardly extendingfoot flanges engaging the bead orf the disk concentrically position thering. Since this ring is in engagement with the inner face of thedemountable rim when the latter engages its seat, the ring assists insupporting the rim upon the disk.

The valve stem and its cap are located at the outside of the disk whichis de ressed as shown particularly in Figure 3.

at this point and the inner flange of the ring is cut away from thepassage of the stem and cap.

In a plying the demountable rim upon the disk, t e ring fulcrums firstabout the inwardly extending foot flanges 23, and as the nuts 18 aretightened, the outer side flange of the ring moves radially. outwardupon the outer bead of the demountable rim until it comes into contactwith the inner face of the base of the rim. At this time, the Outwardlyextending foot flanges 22 of the ring are also in engagement with theouter face of the outwardly dished portion 12 of the disk.

What I claimas my invention is:

1. In a vehicle wheel, the combination with a disk having an outerflared portion forming a seat and a beaded portion, of a demountable rimengageable with said outer flared portion, and a clam engageable withsaid demountable rim an having a flan e terminating 'in peripherallyseparated iver ing foot flanges engageable with said beaded portion toposition said clamp concentrically upon said disk.

2. In a vehicle wheel, the combination with a disk havin anouter flaredportion forming a seat an a beaded portion, of a, demountable rimengageable with said outer flared portion, and a channel-shaped clamphaving an outer flange engageable with said e transverse split in thering also preferably occurs demountable rim, and an inner flan eterminating in peripherally separated iverging foot flanges engageablewith said beaded portion to position said clamp concentrically upon saidisk.

3. Ina vehicle wheel, the combination with a disk having an outer flaredportion, an outer annular portion connecting into. said flared portion,a dished portion connecting into said annular portion, of a demountablerim adapted to seat upon said outer flared portion, a channel shapedtransversely split ring having an outer flange engageable with saiddemountable rim,- and an inner flange terminating in peripherallyseparated outwardly and inwardly extending foot flanges engageable-withsaid dished portion to posi tion said ring concentrically upon saiddisk, bolts extending transversely of and secured 29 to said outerannular portion and extending freely through the base of said ring, and

nuts threadedly engaging said bolts and adapted to abut the base of saidring for laterally moving the same toward said annular portion.

4. In a Vehicle wheel, 'a Wheel body having a flared seat and a radiallyinwardly spaced.

flange transversely-sheared to terminate in peripherally separateddiverging foot flanges engageable with said beaded portion to positionsaid ring concentrically upon said wheel body.

In testimony whereof I afiix my signature.

WILLIAM N. BOOTH.
